"Ira was cordial and professional. He has practical experience and knowledge of residential energy audits. He was able to provide useful suggestions but not definitive solutions to issues. That may have been due to inaccessible interior walls. I am frustrated that a full written report that had been promised still has not been produced six weeks later."

"On Saturday afternoon my heat went off. Called Adem because he had done some minor work for me previously and I was satisfied. He came over Sunday morning (even though it was his day off), checked out the situation, and made recommendations. I called him several times on Sunday and he patiently answered all my questions. No pressure. I decided what to do, he showed up promptly on Monday morning with the new furnace, and by that afternoon I had heat again. He finished tying up remaining details of the job on Tuesday and will take care of the required permits for me. When cooling season begins, he'll get my AC up and running. I'm very satisfied with Adem's professionalism, expertise, and prompt response in restoring heat to my home just before temps plummeted into the single digits."

"Person who visited was very polite and noted that what I purchased was likely not something that would meet my expectations.  I wanted an energy audit, how my systems could be improved in home, lighting, heating, insulation and air conditioners.  What I got was a list of things they could work on and the price to do that work.  The work list in no way was considered an energy audit, rather it was a punch list of things I could do based on their visual inspection.  I did not have a comparison of work and benefit/savings calculation.  There was no checklist of inefficiencies and how that translated into energy losses. For example, multiple hi hat lights in house, they spoke about boxing and insulating a few, less than 10, when I have almost 90 in house.  Overall I was disappointed, the tech who came said the offering needed to be better presented prior to start of work."

"RC came out to service the hot water heater at my house in South Jersey last year. Even though it was an old unit, no one tried to coerce me into purchasing a new heater, which would have been out of my budget. They arrived in a very timely manner, the employees were knowledgeable and professional, and the problem was fixed immediately. I would recommend them to anyone!"

Energy Efficiency Auditing FAQs, answered by experts

Solar water heating systems are not one-size-fits-all. You'll likely work with a team of experts to get the job done—including solar panel installers, plumbers, and water heater installers. A specialist will help you decide if a passive or active system is best for your local weather, home layout, roof stability, and your budget.

The three levels of home energy audits include:

There are energy-efficient options when building a cottage. Select green building materials, high-performance insulation, and energy-efficient windows when designing your cottage.
